Catalin Marinas f5886c7f96 kmemleak: Protect the seq start/next/stop sequence by rcu_read_lock() ...

Objects passed to kmemleak_seq_next() have an incremented reference
count (hence not freed) but they may point via object_list.next to
other freed objects. To avoid this, the whole start/next/stop sequence
must be protected by rcu_read_lock().
